One
of these countries, most probably France, will veto
the resolution. If there are 9 votes supporting the
resolution, the UK and US will cite this as an unreasonable
veto going against the will of the Security
Council.

These
countries will work to try and make sure that the
US and UK do not get the 9 votes required to pass
the resolution, thus avoiding the need to use their
veto.

It
is almost impossible that Russia or China will use their
veto, which leaves only France. The fact that France
is frantically going around the African countries on
the Security Council trying to convince them to vote
against the resolution, suggests that they are not really
prepared to use their veto and are actually going down
the second route.
